Invest some feeling into the handshake and pleasantries, even if you think you bombed the interview. The interviewer should give you a time frame for when to expect to get a callback, if applicable.
★ Hold your head high and keep your cool. Your emotions are probably teetering at the highest of highs or the lowest of lows, but try to stay measured. Project a cool confidence - not cockiness - and walk out of the interview with your head held high.
★ If the interviewer does not tell you when they will contact you if you're a good fit for the position, it's appropriate to ask, "When can I expect to hear back from you about the position?" This will prove important later on.
Try to come off as a genuinely likable person if you can. If you're cynical, pessimistic, and absolutely disabused of any faith in humanity, try to tone it down during the interview. Being personable is about getting the interviewer's emotional side to like you and believe in you. Employers don't always hire the candidates most qualified for the job, but rather the candidates they like the best.
Don't criticize your former employer. When you're talking about your past experience, be courteous about your former places of employment. Be honest about your experience - what you liked and disliked - but don't indict your former boss unnecessarily. Your class and restraint will shine through.
Talk about what other people think you do well. Don't add the preamble, "My friends think I'm a competent social organizer." Just go out and say it with the right touch of confidence and humility. Women tend to underestimate their overall job performance, so be aware of that before you second-guess or undercut yourself, because it's unlikely to get you a job.
Talking about yourself can be very difficult to do well: You're trying to convince someone you don't know that you're qualified for a position without sounding too cocky or pompous. Stick to what you know well, and keep things short and sweet.
Don't use slang or off-color humor during your interview. It's important not to say "awesome" or "rad" during an interview, unless you're interviewing for the local lifeguard position. It's also a good rule to avoid off-color humor; you never know when someone might take offense, and it's best not to risk it.
Structure your answers so that you're talking in 30-90 second chunks. Any less and you're likely to seem unqualified; any more and your interviewer is likely to lose interest in what you're saying. In the "tell me about yourself" question, highlight 2-3 illustrative examples about yourself before wrapping up.
In a pinch, take a cue from politicians. When a politician hears a question they don't like, they simply answer a different question. You don't want to do this all the time, but you can do it in a pinch.
Many people think that an interview is the perfect time to embellish. While you want to structure your answers so that your best, most qualified aspects take center stage, you don't want to deceive or outright lie. Companies do perform background checks, and lying about your experience is simply not worth it.
Don't noodle around on your phone or electronic device while waiting. In fact, leave it in your car. Even though it's practically acceptable, playing around on your phone can communicate boredom and frivolousness (even if that's not the case). Stick with a book or review your notes while waiting.
